Morrison finished in an impressive fifth place in the elite women’s race, completing the 3.8km swim, 180km cycle and 26.2-mile marathon run in nine hours, 12 minutes and 49 seconds.

That has made the Tri-Anglia member, from Bale, near Fakenham, the 14th fastest British women to complete an Ironman – which is still topped by Norfolk’s Chrissie Wellington, who completed Challenge Roth in Germany in 08:18.13 hours back in 2011.

The result was a major success in Morrison’s career, having enjoyed success in Ironman70.3 events around the globe since turning professional in September 2015, as she sets her sights on qualifying for the World Ironman Championships next year.

“I am so delighted to be an Ironman and to race the race at the sharp end,” Morrison said in a short blog post after the race. “A sub-nine-hour Ironman is on every pro athlete’s wish list so to get so close my first time of trying give me great promise and motivation.

“Thank you all so much for the support this season, I absolutely love sharing my ambitions and achievements to those that follow me.”

Norfolk’s other pro triathlon star, Joe Skipper, also enjoyed success in Barcelona as he finished sixth in the elite men’s race.
